May 22 2023 (Monday) Ottawa Spring Migrants Leader: Bernie Ladouceur. Twelve participants including, the leader, found 86 species. Once again, this half-day trip explored the Lac Deschênes IBA. After we met at the Lincoln Fields Shopping Centre, where we had our only House Sparrow of the day, we headed to the Britannia Conservation Area (Mud Lake). Here we found 59 species in just under three hours, including 16 species of warbler. We were patient to get good views of a number of them, including Tennessee, Magnolia, Bay-breasted, Blackburnian, Blackpoll, and Wilson’s Warblers. Other highlights included a heard-only (for most) Mourning Warbler, a late-migrating Blue-headed Vireo, singing Swainson’s and Wood Thrushes, and a flyby Gadwall. Next, was a short stop at the Shirley’s Bay boat launch. An adult and a yearling Bald Eagle, and a Common Loon were the highlights. Finally, we walked a good length of the Greenbelt Pathway West (about 3.7 kms round trip), starting at the Carling Avenue entrance and ending at the start of an extensive field north of Highway 417. At both ends of the walk, we were treated to a good show by Bobolinks, with Eastern Meadowlarks joining in at the start of our walk, and a Northern Harrier putting in an appearance at the far (south) end. In between, the trees progressively became taller; highlights included a drumming Ruffed Grouse, a cooperative Green Heron, a persistently singing Brown Trasher, plus excellent views of both male and female Rose-breasted Grosbeaks and Scarlet Tanagers. The female tanager was especially accommodating because she was continually returning to a caterpillar “tent” to collect nest material (nice, because it’s in my atlas square!). Thanks to all who participated.
